MARTIN FEYBUSCH, OF SEA CLIFF, NEW YORK.

MACHINE FOR COVERING BOXES.

Application filed May 29, 1918.

T 0 all whom it may concern:

Be it known that I, MARTIN FEYBUSCH, a citizen of the German Empire, anda'residentof Sea Clifi, in the county of Nassau and State of New York,have invented certain new and useful Improvements in Machines forCovering Boxes, of which the following is a specification.

This invention relates to a machine of novel construction by means ofwhich the bottom and sides of square or oblong paper or other boxes areprovided with a paper covering which is pasted thereto, and is lappedover the edges thereof.- The machine is designed to be supplied with boxbodies, and with cruciform covering blanks, the four wings of the latterbein lapped over the sides of the box bodies. The invention consists inthe various features of novelty more fully pointed out in thespecification and appended claims. 7

During the preceding operation, the two side wings of the blank whichwere turned over the two sides of the box, were left projecting a shortdistance beyond the ends of the latter to form four protruding flaps E.By operation four, these flaps are first turned in against the uncoveredbox sides,

and then the latter are covered by the two remaining wings of the blank.To efi'ect these results, there is provided a' plunger 57 intermittentlyoperable from shaft 5 by closed cam 58, lever 59, 1ink 60 and clamp 61,aspring 62 being preferably employed to assist the upward movement ofthe plunger. WVithin the head of plunger 57 is mounted a disk 63 whichis adapted to be oscillated from shaft 5, by cam 64, rod 65, finger 66,slide 67 and a pin 68, which extends upwardly from the disk and enters aslot 69 of the slide. Disk 63 is provided with a pair of eccentric slots70 engaged by rollers 71 carried by a pair of opposed slides 72, whichby the oscillation of the disk, are simultaneously reciprocated towardor away from each other. Each slide is furnished with a pair of inwardlyextending resilient fingers or folders 73 that are adapted to straddlethe box. Upon the inward movement of the slides, the fingers will pushthe flaps E against the still uncovered sides of box A, and paste themthereto by the pressure exercised by said fingers. Immediately precedingthis operation, the two covered sides of the box are engaged by a pairof pressure rolls 74 that upon the descent of the plunger. pass over thepreviously glued wings C and thus press them tightly against the sidesof the box. Rolls 74'are hung below the lower operative ends of fingers7 3 and are carried by arms 75 fulcrumed at 76 and drawn toward eachother by a spring 77. V g

After the flaps E have been turned against the uncovered sides of thebox, the wings D of the covering blank B that extend at right angles towings C are folded and pasted against said sides. This operation iseffected by means of a pair of pressure rolls 78 extending at rightangles to rolls 74, and hung within a higher horizontal plane than thelatter, and also in a higher plane than the inner operative ends of"fingers 73. Rolls 78 are similar to rolls 74, carried by arms 79fulcrumed at 80 and drawn toward each other by a spring 81. When plunger57 descends, pressure rolls 74 first engage the covered sides of the boxand roll down along the same as previously described. The plunger thenstops and the BEST AVAILABLE coPY B fingers 73 which have been broughtinto position opposite flaps E are moved inwardly to turn said flapsagainst the uncovered sides of the box, and a e then immediatelywithdrawn.

The plunger resumes its downward movement and thereby causes rolls 78 tofold wings D over flaps E, and over the previously uncovered sides ofthe box, and to paste them thereto. Prior to the ascent of plunger 57,rolls 74 aswell as rolls 78 must be spread apart to clear the box. Thisspreading of therolls is efiected as follows: Power shaft 82 by chaindrive 83 turns a countershaft 84, which by cam 85 raises and lowers arod 86 provided at its upper end with a roller 87. This roller engages atappet 88 on a rock shaft 89, carrying a pair of cams 90 and a secondpair of cams 91. Of these, cams 90 are engaged by rollers 92 at the endsof slotted links 93 that encompass shaft 89, and are connected at theirouter ends to the arms 75 of rolls 74 above fulcrums 76. Cams 91 engagearms 79 of rolls 78 above fulcrums 80. Thus upon the upward movement ofrod 86, shaft 89 will be so turned, as to spread rolls 74 against actionof spring 77, and rolls7 8 against action of spring 81. The rolls havingthus cleared the box, plunger 57 ascends, and during such ascent tappet88 engages a fixed abutment 94, by means of which shaft 89 is so rocked,as to move rolls 74 and 78 back into their inner or normal position.

In order to hold the box to the core 9 while the covering operation isgoing on, the rod ofplunger 57, is made tubular to receive a rod 95carrying ahead 96, having a pad 97. The latter is apertured for thereception of a spindle 98 carrying a presser foot 99 which is influencedby a spring 100. llhen the plunger 57.des'cends, pad 97 bears on boxAthrough action of a s ring 101. lVhen the plunger rises, the pad iswithdrawn prior to the withdrawal of resser foot 99, for the reasonstated when discussing presser foot 58. It should be stated that in thisstation, roller 12, engages a raised support 102.

Station No. 5, (Figs. 24-28.)

A plunger 103 is intermittently reciprocated from shaft 5 by cam 104,lever 105, and link 106. WVithin the plunger head is fittedanoscillatable disk 107 having eccentric slots 108, engaged by rollers 109of two pair of opposed blade holders or slides 110. Each of theseholders carries at its lower end, an inwardly projecting horizontalblade or folder 111, adapted to turn the protruding end of each winghorizontally across the lower edge of the respective box side. Disk 107is operated from shaft 5 by cam 112, link 113, finger 114, slide 115 andpin 116 that engages a slot 117 of the slide. From the center of theplunger head. there depends a sleeve 11H carrying a plunger 119 providedwith a pad 121) and furnished with a springinfiuenced presser foot 121.in manner described withreference to stations 3 and 1.,

llunger 119 is surrounded by four guide 7 plates 122 arranged atrightangles to each other and depending from plunger Below the latter. platelO is adapted to be 'raised off core 9 by means of a finger 123 whichunderlies roller 12. and is operated from shaft by cam 124rlever 125 rod126 and link 127 turning on shaft 128.

\Vhen the box arrives at station 5. plunger 103 descends untilpad 120rests against .the upper side of the box. Plate 10 thenrises to lift thebox off the core 9. the box in' turn raising pad 120. Blades 111 uowmove inward to turn the protruding edges of wings (I and'D horizontallyacross the edge of the box body. two of the blades being set slightlyabove the other two to prevent interfering. T heblades are withdrawn andplunger head 103 descends, together with pad 120. At the same time,plate 10 is lowered upon core 9 by the descent of fingerv 123. sothat-in this way. the box is again projected over-coret). As the box isthus being moved over the core, the latter will turn the protrudingedges of the wings C aml D upward and against the inner faces of the boxsides. to which they-will become glued. After this action has beeneompleted.plunger 103' as well as pad 120'rises, while. plate-10 remainsdepressed ready for the next operation.

A plunger 129 operated by ram 129*. arm 129". and link 129. carries anoseillatable disk. 130, having" eccentric slots 131 which are. engagedby rollers-132 of two pair of opposed slides 1 Each slide earriesjat itslower end, a presser jaw 13+, adapted to engage one of the sides of thebox throughoutthe entirelength and height'thereof, and

provided with a padded inner working face.

Disk 130 is oscillated from shaft 5 by cam" lever 136,"finger 1 37.slide 138, and pin 139. To the lower side of plunger 129 is affixed apad .110. Plunger 129 descends until pad 140 rests on the box and thenthe four slides 133 are moved inwardly. so that the padded faces of jaws134 will bear firmly against all the four sides of the box, and pressthem against core 9. In this way, the

bottom of the box. as well as its four sides are simultaneouslysubjected to pressure, ,in

order to smoothen out all parts of the covering and insure a neatfinish.

For the purpose of locking brackets 7. at

their different stations and to relieve them of undue pressure, they areprovided with mortises 141 into which pins 112 are adapted. to beprojected. These pins extend in- BEST AVAILABLE COPY wardly from alongitudinallygdisposed horizontal bar 113, which is connected at itsends I to a pair of oscilla'ble arms 141, turning on centers 11:). Oneofthese arms is adapted to be rocked from shaft 5 bv cam 11 6, lever H7,rod 118, and arm 14%).- The t'in'iing is such that pins 1+2 entermortiseslll when the brackets 7 are at rest. and prior to the movementof the, several plunge'rs. while they are 'wlthdrawi'i directly before.thebrackets resume. their motion.

by a plurality of spring hooks 153 which pass beneath the lower edge ofthe box. The

box is then engagedby a pusher 151 which slides the same oft hooks 15 3and upon plate 152. This pusher is operated from shaft 5,

by cam 155, arm 156, lever 157, and slide 158. The pusher is providedwith a-pair of overhead horizontally disposed spring arms v 159, whichcheck the upward movement of the box, while the same is being raised,and furthermore constitute guides while the box is being slid by thepusherfrom the hooks upon the delivery plate.

It is of course, obvious that a number of boxes will be .siniultaneouslyput through the machine, and that the latter is adapted to operate on'box covers as Well asbox bodies. the word box in the claims, beingintended to embrace both devices.

The machine is adapted to cover boxes made ofpaper aswell as those mad'eof sheet metal. wood, fiber or other material. It is also adapted toinwrap' boxes or 'con-' tainers that have been previously charged andclosed by a cover, thusproducing a sanitary dust proof package.
